Session Trouble

Hi, I just moved to DreamHost and I’m having a huge problem with my site. I’m getting an error that I don’t understand. It has something to do with the session_start() that I’m performing to instantiate my shopping cart. Any help would be greatly appreciated.

Here’s the page that shows the errors I’m getting.

P.S. I just transferred the nameservers around noon today, so hopefully that won’t cause any trouble, seeing as how the servers may still be kicking in.

Ok, I feel really dumb now. I was sweating to death over nothing. I had a cookie in my browser from the previous server. So the server path was all wrong. ha ha =)

Ok, I’m going to have to take that back again. I’m still having the same problem. When I delete the cookie, it works in initially creating the cookie/session, but when it tries to make another call to it on another page, it throws up an error message.

help =(

While not an expert on this subject, I think my input might help a light go on for somebody reading this. You seem to have a mismatch in your configuration somewhere. Cookies from “” and “” are not interchangeable.

You have your domain set up to always add “www”. If I go to, my browser settings show a session cookie with the correct value, but there are some differences. The site is listed as “” but the HOST value for the cookie is “

That causes your site to throw the following error:

If I clear my cookies and then browse to, the new browser cookie shows for both site and HOST. The error then goes away, and everything seems fine. As soon as I click a link, the session blows up and I get the same error message. When I check my cookies again, I see the site has been reset to, and no longer matches the HOST.

What happens if you configure your domain to always remove “www” in the DH panel?
